(Discontinued) A random teenager dies, and no they don't get hit by the Isekai truck unfortunately. The 'driver' couldn't make it on time. This teenager wasn't really random, they were kept in a lot of people's hearts but unfortunately, all good people come to an early demise. Problems arise, something is clearly off with everything. Was this all planned all along? What would the gods think about this newly reincarnated soul in the body of a powerful being? What would YOU do? Hey what about that purple thing- ⚠️Warning⚠️: In this book there is certainly angst in it so I'm adding this warning. This book contains multiple examples of (but not limited to): • Mentions of Torture • SA • Gore • Violence • Suicidal Thoughts • Attempted Suicide But not to worry readers, there are also good things such as Fluff relationship. After all, every book contains some bad scenes and because Dream and Night has bad backstories. Feel free to ask any questions and I will answer it.

Error. Everything was taken away from him, his world, his brother, Everything. What he got after that was a life he never wanted. He earned names like Destroyer of worlds, murderer, and many more. He still protected them from the thing they never feared: Creation. He gave up a long time ago, but when he gave up on protecting the multiverse, He expected Death. But instead, he was given freedom from the chains that bound him. "𝓣𝓪𝓴𝓮 𝓽𝓸 𝓽𝓱𝓮 𝓼𝓴𝔂𝓼, 𝓞𝓤𝓡 𝓬𝓱𝓲𝓵𝓭𝓻𝓮𝓷..." HWHBB Error and Orig!Universe characters are credited to Harrish6 Please read Theirs before mine. (Warning, slow and random updates)
